Collegiate domain?

EDU

Think of the three letters that often follow a dot in university website addresses.

"Collegiate domain?" is a playful hint pointing to ".edu," the top-level domain used in web addresses for American colleges and universities (like harvard.edu). The word "domain" here isn’t about land or authority—it’s the internet suffix tied to education. The clue’s question mark signals a pun, since "collegiate" literally describes schools while also nodding to their online home. Short, clever, and to the point: "EDU" fits perfectly.
